Description

technical field

[0001] The present invention relates to the field of television, and in particular to service management in a network of televisions, such as those found in public places like hotels, hospitals, train stations etc., in order to control the display and access rights of televisions to multimedia services and streams. Previous art

[0002] Public places such as hotels, hospitals, campsites, schools, and other communities often use networks of televisions connected to a central receiver or "injector" of multimedia streams. Each television has access to specific multimedia channels, which the user can select.

[0003] The media stream injector is generally a box connected to media stream sources such as a satellite dish, a digital terrestrial television (DTT) connection, an IP connection to an internet digital television server, etc. These sources generate individual media content channels, often thematic and / or intended for different users.

[0004] For example, a number of these channels may be made available to all users, while some channels or "packages" of channels require the user to have paid an additional subscription in order to acquire access rights to these channels.

[0005] A specific television may also have only one channel available, for example, to loop a welcome message in an entrance, or an informational message about the location of the television.

[0006] Multimedia channels or streams are emitted from a source which is for example a satellite (DVB-S), cable (DVB-C) or terrestrial (DVB-T) television signal receiver box.

[0007] So-called "smart" or connected TVs use IP (Internet Protocol) networks for this purpose and therefore require Ethernet connectors or a wireless connection such as WiFi, forming a service called "IPTV".

[0008] The menus for displaying, selecting, and acquiring access rights for televisions are managed via HTTP (HyperText Transfer Protocol) internet protocols over Ethernet and Wi-Fi networks, using a well-established method. This involves bidirectional communication between individual televisions and a central unit that acts as both a multimedia stream source and access rights manager. Various Conditional Access (CA) systems, such as the DVB (Digital Video Broadcasting) standard, exist. These systems encrypt channels but do not allow for a specific graphical interface, and the names of encrypted channels remain displayed in the channel guide even when they are unavailable to the user.

[0009] However, some places or buildings do not have dedicated Ethernet networks for televisions, but have simple coaxial cables, which do not allow for the establishment of bidirectional communication of the "IPTV" type.

[0010] DOCSIS (Data Over Cable Service Interface Specification) technology provides an equivalent service, but at the cost of a modem device at each television. Configuring the resulting coaxial network is complex and deployment takes longer. Furthermore, the network is relatively energy-intensive, and the modems are sometimes damaged and require maintenance.

[0011] DOCSIS and DVB-CA solutions also rely on encryption and decryption using smart cards or USB keys, which can be stolen or lost.

[0012] Standards such as HbbTV (Hybrid Broadcast Broadband Television) in so-called "broadcast" mode allow the display of interactive menus and specific information locally on a television with unidirectional communication, but notably without return communication, from the television to the multimedia stream injector.

[0013] It would be particularly interesting to be able to emulate two-way communication television services such as IPTV on these coaxial cable networks, without the previously mentioned disadvantages (energy consumption, additional modems and keys, etc.). Summary of the invention

[0014] To address this need, the invention proposes a multimedia stream control device for televisions, comprising: a multimedia stream injector, comprising: * at least one multimedia content source, * at least one means for generating a multimedia stream containing one or more applications and individual multimedia content from the sources, * electronic memory and at least one electronic means for executing programs enabling the storage and modification of information on said electronic memory, at least one television, connected to the multimedia stream injector through a radio frequency terrestrial or cable television distribution network comprising: * electronic memory and means for executing applications enabling the storage and modification of information on said electronic memory, * means for displaying specific multimedia content on the television.

[0015] The device according to the invention can be implemented, in particular, as a one-way downlink transmission network from the injector to the televisions. In the multimedia stream control device for televisions: The electronic memory of each television contains a television identifier; the electronic memory of the multimedia stream injector contains a table, containing a list of accessible multimedia content and application execution methods for each of the televisions identified by their identifiers. the media stream injector being configured to transmit to each of the TVs the table containing the lists of media content accessible to each of the TVs and the media stream, and the TVs being configured to display or run the applications and media content accessible according to their identifier.

[0016] Furthermore, in the multimedia stream control system on televisions: The televisions and the injector are equipped with means for executing HbbTV protocols, the multimedia stream includes a DSM-CC carousel containing data that can be downloaded by the televisions, said DSM-CC carousel includes one or more encapsulated HbbTV applications which, when executed by the television, configure the televisions in a specific way, each television being able to be configured to execute the applications differently according to its own identifier, by means of the table containing the lists of multimedia content accessible by each of the televisions.

[0017] Thus, despite the purely one-way nature of the data transmission and the single multimedia stream within the network, each television exhibits unique and programmable behavior via the injector. No additional demodulator or modem is required on the televisions.

[0018] This configuration allows the individual behavior of each television to be programmed solely by means of its identifier, without direct intervention on the television.

[0019] Furthermore, integrating the rights and accessible content table into the DSM CC carousel with HbbTV compatibility on televisions allows for near-instantaneous, continuous updates of rights due to the carousel's push and regularly consulted nature, without requiring application restarts. In addition, since communication remains within the HbbTV environment, access security is enhanced.

[0020] The device according to the invention may also have one or more of the following characteristics, taken alone or in combination.

[0021] The media stream injector may include: a connection to a computer network comprising a server connected to the injector, means for generating multimedia content comprising a computer address of the server for display on one or more of the televisions of the computer address, and access to the server by means of a user terminal via the network by means of the computer address giving access to interactive menus for modifying the list of multimedia content accessible to the television.

[0022] The multimedia stream injector may include, in particular: a connection to a computer network comprising a server connected to the injector and means for generating multimedia content comprising a computer address of the server for display on at least one of the televisions of the computer address, access to the server by means of a user terminal via the network by means of the computer address giving access to interactive menus for modifying the list of multimedia content accessible to the television.

[0023] The user can then modify the rights and settings of the television using the user terminal, which may include their phone, possibly with an associated payment.

[0024] The computer network can be, in particular, an internet or intranet network, and the displayed address can then be an IP address, which can be displayed in encoded form such as a QR code. The media stream injector can then be configured to detect a change in the table of accessible media content lists, and, when a change to the table is detected, to send the modified table to the televisions.

[0025] Alternatively, the media stream injector can be configured to send the list table of accessible media content to TVs at regular intervals.

[0026] The television may include: a multimedia stream receiver, said multimedia stream being composed of encapsulated data packets, containing on the one hand media and on the other hand applications in the form of executable instructions which, when executed, program the behavior of the television, with applications associated with one or more of the television identifiers, the receiver being configured to isolate and separate the media from the applications, an application manager, configured to download said data into the television's memory and then execute it as computer programs, which receives the applications isolated by the receiver, a multimedia file manager, configured by means of the applications downloaded and executed by the application manager, the multimedia file manager being configured to filter accessible media from inaccessible media among the media in the multimedia stream, a browser,which displays the accessible media from the multimedia stream in menus configured using the applications.

[0027] The multimedia stream can then be, in particular, one or more MPTS streams.

[0028] The volatile electronic memory of each television is configured to store information, particularly related to access rights and applications.

[0029] The invention further relates to the method of managing multimedia streams associated with a multimedia stream injector for a television in a device as previously described, comprising the following steps: In an initialization phase, communication of an identifier for each of the televisions, stored in the electronic memory of the television, to the multimedia stream injector, storage in an electronic memory of the identifiers of the televisions by the injector and generation by the injector of a table of lists of multimedia content accessible by the televisions identified with their identifier, sending the table to the televisions and storage in the electronic memory of the televisions of the list of multimedia content accessible to their identifier contained in the table, display or execution by the televisions only of the content accessible from the list associated with their identifier.

[0030] The identifier of each television can, during the initialization phase, be generated pseudo-randomly and stored on an electronic memory of the television.

[0031] The multimedia stream injector may include a connection to a computer network comprising a server with access to the computer memory of the multimedia stream injector containing the list of accessible multimedia content from at least one of the televisions and means of modifying the list of accessible multimedia content from said television.

[0032] The process may then also include the following steps: generation of multimedia content including the computer address in the server's network, display on the television of the multimedia content including the server's computer address to allow the user to modify the list of content accessible to the television by means of a user terminal connected to the server via the computer address displayed in the multimedia content, sending by the multimedia stream injector of the modified list of accessible multimedia content to the televisions.

[0033] The invention also relates to the computer program product comprising instructions whose execution by a computer part of or connected to the device previously described causes said device to execute the steps of the above process. Brief description of the figures

[0034] Other advantages and features of the invention will become apparent from the description of the figures below, including: there [ Fig. 1 ] is a diagram of the components of the network of televisions connected to the media stream injector, the [ Fig. 2 ] is an organizational chart schematically outlining the main steps in the network management process of the figure 1 , there [ Fig. 3 [ ] is an organizational chart of a variant of the management process of the figure 2 , there [ Fig. 4 ] is a functional flowchart of the various components of a television for the network of the figure 1 .

[0035] The embodiments shown are given as illustrative and non-limiting examples. Other embodiments may be obtained, in particular by variation or combination of the embodiments shown. Detailed description of the figures

[0036] There figure 1 is a schematic representation of a multimedia flow control device 100 F. The device 100 includes a multimedia content injector 1, connected to sources S1, S2, S3. These sources are, for example, an internet box S1, connected to a digital television service via the internet, a digital terrestrial antenna S2, a satellite antenna S3.

[0037] Each of these sources broadcasts multimedia content in the form of streams or channels, grouped into channel bouquets, and specific applications, for example in the form of sets of instructions, menus and content to be displayed sequentially and with which the user can interact.

[0038] The HbbTV standard allows, in particular, the management of such applications, including in "Broadcast" mode for unidirectional broadcasting.

[0039] Injector 1 can group these bouquets into a multimedia stream F sent for example via at least one coaxial cable, notably with an impedance of 50 or 75 ohms, with an antenna connector ( IEC 61169-2) or "F-plug", via a Radio Frequency RF (VHF / UHF) terrestrial or cable television distribution network, to televisions 10. The multimedia F stream may include one or more MPTS streams transmitted on one or more frequencies.

[0040] At least part of the transmissions can, as an alternative or complement, pass through analog RF radio frequency transmitters and receivers.

[0041] Injector 1 can notably be in the form of a multimedia stream management computer, equipped with a Radio Frequency output for injection into the Radio Frequency network.

[0042] Two 10-inch TVs are shown, but a larger number of 10-inch TVs is of course possible.

[0043] These televisions 10 include, in particular, electronic memories and means for executing specific programs and instructions allowing the content of these memories to be modified and specific content to be displayed from the multimedia stream F or content to be generated from the content of their electronic memory and instructions contained in the multimedia stream F.

[0044] Each television 10 is identified by a unique identifier Id1, Id2 in the radio frequency distribution network, stored in the television 10's internal memory. The identifier Id1, Id2 can be generated pseudo-randomly. The injector 1 contains a list of the identifiers Id1, Id2, communicated to the injector during the installation of the televisions 10 or when a television 10 is added to the device 100.

[0045] Each TV 10 can have its own unique identifier Id1, Id2, or TV 10s whose behavior must be identical can have the same identifier Id1, Id2.

[0046] Alternatively, the identifiers Id1, Id2 can be encoded in an electronic component (“hardware”) during the manufacture of televisions 10.

[0047] Injector 1 generates or stores in an electronic memory a table Tab of identifiers Id1, Id2 with for each of the identified televisions 10 a list of accessible and inaccessible content in the multimedia stream F.

[0048] The Tab table is sent to the televisions 10 which isolate in it the list relating to their identifier Id1, Id2, and filter accordingly the contents of the multimedia stream F.

[0049] For example, one of the TVs 10 may have access to a larger set of channels as part of a higher quality or "premium" service, for example a more expensive hotel room, or thematic channels, related to the location or the expected audience of TV 10.

[0050] The multimedia stream F can notably contain instructions for customizing the menus and content displayed by the TV 10. For example, the display language of menus and media, the order of TV channels in the accessible package, and the definition of images of multimedia content can be controlled by the multimedia stream F via these instructions.

[0051] Furthermore, the multimedia stream F can include one or more applications, in the form of instructions executable by the TVs 10, to program the behavior of said TVs 10. The table Tab then contains, for each TV 10 identifier Id1, Id2, specific execution methods for the applications. Thus, each TV 10 executes or does not execute a specific part of the application(s), or executes the application(s) with specific parameters and access rights, according to its identifier Id1, Id2.

[0052] The Tab table of TVs 10 and the content they display and run or not can be made accessible and modifiable by a user terminal 7 such as a computer, tablet or phone connected to the multimedia stream injector 1 F, including the editing of specific profiles, each having a set of accessible multimedia content and applications to run to personalize the TV 10 and the service associated with it.

[0053] To allow a user of a television 10 to modify the multimedia content list of the associated Tab table, the multimedia stream injector 1 F includes a connection to a computer server 3 of a computer network net and means of generating multimedia content containing a computer address 5, corresponding to server 3 of the computer network net.

[0054] For example, computer address 5 is displayed as an IP (Internet Protocol) address of the URL (Uniform Resource Locator) type if the network net is an internet or intranet network, or a quick access code such as a QR code or barcode.

[0055] The user can then use a user terminal 7, such as a phone, tablet, or laptop, to connect to the server 3 using the address provided to them. The computer server 3 gives the user access to the computer memory of the multimedia stream injector 1 F, which contains the list of multimedia content accessible to the television 10 displaying the computer address 5, and includes means of modifying this list, for example, in the form of an interactive menu to select a profile or unlock options.

[0056] In particular, the computer server 3 may include an application for billing, payment or connection to a payment terminal, and make some access to predetermined content or sets of content conditional on payment.

[0057] The F multimedia stream injector 1 can then be configured to detect a change in the Tab table containing the lists of accessible multimedia content, and then send the Tab table containing the modified list to the TVs 10 via the F multimedia stream.

[0058] Alternatively, injector 1 can send the Tab table at regular intervals to the TVs 10, whether it has been modified or not.

[0059] There figure 2 is an organizational chart outlining the main steps of the multimedia stream management process 200 F using device 100 of the figure 1 .

[0060] The first step 201 is the generation, during initialization upon installation of the device 100 or when adding one or more televisions 10, of the identifier Id1, Id2 specific to each television 10, for example by pseudo-random generation, and the storage of said identifier Id1, Id2 in the memory of the television 10. The identifiers Id1, Id2 are communicated, for example via an installer or administrator of the device 100, to the injector 1, which stores them in its memory. In a second step 203, the injector 1 stores the identifiers in its own memory and generates, for each of the identifiers Id1, Id2, a list of multimedia content accessible in the transmitted multimedia stream F, thus composing the table Tab.

[0061] In a third step 205, the table Tab containing the identifiers Id1, Id2 and the list of multimedia content accessible to each of the identified TVs 10 is then sent to the TVs 10 with the multimedia stream F, so that each TV 10 stores in its memory the list of content it has access to, which is part of the table Tab. Access rights to content and applications are stored in volatile memory within the electronic memory of each TV. In the fourth step 207, the TVs 10 then filter the content of the multimedia stream F according to the list that has been transmitted to them.

[0062] There figure 3 illustrates a variant of process 300, for a device 100 which includes a connection via the computer network netto a server 3 presenting access to the computer memory of the multimedia stream injector 1 F containing a list of accessible multimedia content from at least one of the televisions 10, and means for modifying the list of multimedia content accessible to said television 10.

[0063] The first two steps 301, 303 are identical to the first two steps 201, 203 of process 200 of the figure 2 and correspond respectively to the initialization with communication of the identifiers Id1, Id2, and to the generation of the Tab table: generation, during initialization at the installation of device 100 or when adding one or more TVs 10, of the identifier Id1, Id2 specific to each TV 10, and the storage in the memory of TV 10 of said identifier Id1, Id2 and storage of the identifiers in its own memory by the injector, and generation for each of the identifiers Id1, Id2 of a list of multimedia content accessible in the multimedia stream F emitted to form the table Tab.

[0064] During the third step 305 of sending the table Tab and the multimedia stream F by injector 1, injector 1 also sends multimedia content including the computer address 5 of the server 3 to the TV 10 with instructions to allow the user of the TV 10 to connect a user terminal to the server, for example by integrating the display of the address into a specific application with different menus and access paths so that the user of the TV 10 can be invited to modify the accessible content of the TV 10.

[0065] During the fourth stage 307 of filtering the content by the TV 10 according to the list of accessible content, a display on the screen of the multimedia content containing the computer address 5 of the server 3 is then made possible or, according to a variant, automatic at each start of the TV 10.

[0066] During a fifth step 309 the user accesses the list relating to a television 10 in the Tab table, and may or may not modify this list of accessible multimedia content.

[0067] Therefore, in a conditional sixth step 311, if the user has modified the list of content accessible from server 3, process 300 returns to the second step 303 of generating and sending the Tab table to the TVs 10 via injector 1, including the modifications made. If the user has not modified the list of content accessible to a TV 10, process 300 returns to the fourth step 307 of filtering the multimedia stream F.

[0068] Televisions 10 and injector 1 can notably be equipped with means of executing HbbTV protocols, in the form of electronic memory and processors to the ETSI TS 102796 standard. The multimedia stream F can then be presented in the form of a multiplexing of services and a DSM-CC carousel (“Digital Storage Management Command and Control”).

[0069] Alternatively or in addition, the multimedia stream F can also include applications, that is, HbbTV instructions and protocols which, when executed by the TV 10, configure the TVs 10 in a specific way. The multimedia stream F can then contain several applications, each associated with an identifier Id1, Id2, with each TV 10 running only the applications associated with its own identifier Id1, Id2.

[0070] It may also be among the same application executed differently, or with different settings and access to different parts of said application by each of the 10 TVs according to its identifier Id1, Id2.

[0071] Applications can then restrict the channels and media accessible to the TV 10, and in particular hide channels and media that the TV 10 does not have access to by excluding them from menus and channel bundles.

[0072] There figure 4 illustrates in the form of a functional flowchart a television 10 configured in this way.

[0073] Television 10 includes a multimedia stream receiver F. This multimedia stream F is composed of encapsulated data packets, containing on the one hand media M in the form of videos, images and sounds, and on the other hand applications App, in the form of executable instructions which, when executed, program the behavior of television 10 (menus, image configuration, sound etc).

[0074] The multimedia stream F is received at a receiver 11 of the television 10, which isolates and separates the media M from the applications App. The applications App are, for example, HbbTV applications, modulated in DVB-C, DVB-C2, DVB-T, or DVB-T2. The media M are, for example, encoded as MPTS (MPEG Transport System) streams.

[0075] The data corresponding to the App applications is then sent to an application manager 13, configured to download said data into the TV's memory and then execute it as computer programs.

[0076] The App applications include instructions concerning the media M of the multimedia stream F. In particular, these instructions may include whether subsets of the media M are accessible or not, for example in the form of bouquets of channels that are accessible or not.

[0077] The media M are then sent to a media file manager 15, configured using the App applications downloaded and run by the application manager 13. The media file manager 15 is then configured to filter accessible media from inaccessible media among the media M in the media stream F.

[0078] The said accessible media are then made available to the TV user 10 by a browser 17, which displays the accessible media in menus configured by means of the App applications.

[0079] The browser 17 then allows the user of the TV 10 to select, using a remote control, from among the accessible media M those which he wishes to display on the TV 10, completely hiding the inaccessible media in the menus transparently to the user of the TV 10.

[0080] The multimedia flow control device 100 thus makes it possible to emulate IPTV type television services in the absence of a physical digital return path from the TVs 10 to the multimedia flow injector 1 F, and a single multimedia flow output path F from the injector 1 to the TVs 10 in a radio frequency type network.
